phpUnit测试elasticsearch结果为空

Question

我正在编写我的应用程序的测试方法，并在我的应用程序中使用弹性搜索。当我运行一个应该使用 elasticsearch 返回值的测试方法时，响应总是空的。我该如何解决这个问题？这是我发送的代码。

public function testGetPosts()

{
    $brand = factory(Brand::class)->create();
    $account = factory(Account::class)->create();
    $post = factory(Post::class)->create();

    $response = $this->actingAs($this->owner)->json(
        'GET',
        ('/api/publish/posts'),
        ['account_id' => [(string) $account->id],
        'skip' => 0]
    );

    $response->assertStatus(200);
}

Answer 1

我知道这篇文章很旧，但我在那里添加了我为这个问题找到的答案。 在查询之前确保您的数据被编入索引所需要做的就是在您刚刚编写的索引上调用refresh。 它强制 ES 索引数据，所以当你查询它时你确定数据就在那里！ 它比作者建议的sleep(1); 更快=)

你可以找到关于它的官方 ElasticSearch 文档here。

希望这会对某人有所帮助。

差不多一年后，我敢肯定你现在已经继续前进了。

你说：

弹性搜索不会索引创建的帖子。它应该被索引 为什么会被索引？当然，除非您有代码可以在您的 setUp() 中建立索引，或者您针对外部 ES 服务器进行测试并假设它始终可用并且包含您正在测试的确切数据。

另一个解决方案是模拟请求，因为 Elasticsearch 返回 JSON。我们需要做的就是模拟一个状态为 200 的 HTTP 请求，并返回 JSON。我们可以将这个 JSON 文件放在我们的 tests/ 目录中，它将包含 Elasticsearch 将返回的示例结果。

一个示例测试是这样的；

$handler = new MockHandler([
    'status' => 200,
    'transfer_stats' => [
        'total_time' => 100
    ],
    'body' => fopen(base_path('tests/Unit/mockelasticsearch.json'), 'r')
]);

$builder = ClientBuilder::create();
$builder->setHosts(['testing']);
$builder->setHandler($handler);
$client = $builder->build();
$response = $client->search([
    'index' => 'my_index',
    'type' => 'my_type',
    'body' => [
        [  
            'query' => [
                'simple_query_string' => [
                    'query' => 'john',
                    'fields' => ['name']
                ]
            ]
        ]
    ]
]);

// Test against the "$response", i.e., $this->assertEquals(2 ...) etc.

然后在 JSON 文件中，您需要根据您的索引进行自定义；

    "total": 5,
    "successful": 5,
